profiling-a-webpage-with-chrome.md

First, start Chrome and open the page you want to profile:

./chrome --js-flags=”--prof” --no-sandbox http://localhost:8080/index.html

Note: This page should do things on-load, simply close Chrome once it's done

Then preprocess the biggest .log file you get: (since the biggest one should be from the main renderer):

v8/tools/linux-tick-processor --preprocess v8.log

This gives you a JSON file which is an analysis of the logs, which you load into profview:

v8/tools/profview/index.html
